  2. Soil Pollution; An Overview • Soil pollution is the contamination of soil by harmful substances. • Pollution occurs when contaminants overload the storage and processing of substances in the soil. • Soil lacking in nutrients leads to less nutritious foods due to the contamination.

  3. Sources of Contamination • Point-source contamination is the cause of pollution in landfills, radioactive waste dump sites, drainage from mining, and vehicular emissions/spills. • Nonpoint-source contamination is caused by chemicals, medication, and microbes.

  4. The Extent of Contamination • Soil pollution may be shallow, from the surface to a depth of 3 feet. • The soil can move through only the top 6 inches of soil. • Any deeper contamination is caused through seepage and flow of water.

  5. Soil Cleanup • The process of removing toxic substances is called remediation. • Current techniques include excavation of contaminated soil, washing the soil, and changing the properties of contaminants to make them less toxic.

  6. Sources of Soil Pollution • Agriculture chemicals such as pesticides, fungicides and herbicides. • The contents of landfills being carried by rain into the soil and water. • Industry pollution heavy metal and chemical pollutants being released. • Feedlots damage soil health through excess manure. • Sewage sludge from treatment facilities.

  7. Effects of Soil Pollution • Water pollution, caused by water running over polluted soil. • Air pollution produced by volatile compounds produced by the polluted earth. • Plant contamination through the soil where the vegetation is grown. Animals who eat the plants get the chemical in their body, which can lead to health issues if eaten. • Reduction of soil health, such as the slowing of plant growth and acidity.

  8. Health Effects from Soil Pollution • Cancer can be caused by pesticides commonly used on agricultural lands. • Neurological problems can be caused in children by lead in the soil. • Tissue damage and irritation can be caused by mercury in the soil.

  9. Methods of Controlling Soil Pollution • Preventing soil erosion by planting new vegetation in areas prone to erosion. • Household chemical disposal through designated waste centers. • The proper use of chemical killers or the use of non-toxic killers.
